Breathing circuit connector for use in anesthesiology
First Claim
1. A breathing circuit connector for coupling the output from an anesthesiology machine to the open input end of an endotracheal tube connector, comprising in combination:
- (a) a body of relatively rigid material, said body having a hollow cylindrical input section adapted for coupling to the output of the anesthesiology machine, said body further having a hollow cylindrical output section adapted for coupling to the open input end of the endotracheal tube connector;
(b) a passageway situated within said body and extending between and connecting said hollow cylindrical input and output sections for providing fluid coupling therebetween;
(c) a first smooth and continuous cylindrical bore portion of uniform diameter situated within and forming an integral part of said hollow cylindrical output section, said first cylindrical bore portion having one end adjacent the output end of said hollow cylindrical output section and having a second end situated within said hollow cylindrical output section; and
(d) a second smooth and continuous cylindrical bore portion of uniform diameter situated within and forming an integral part of said hollow cylindrical output section, said second cylindrical bore portion being coaxial with said first cylindrical bore portion and having one end adjacent the second end of said first cylindrical bore portion, said second cylindrical bore portion having a second end situated internally of said hollow cylindrical output section, the diameter of said first cylindrical bore portion being slightly larger than the diameter of said second cylindrical bore portion the difference between the diameter of said first bore portion and the diameter of said second bore portion being approximately 0.05 to 0.1 millimeter.

Abstract
A breathing circuit connector for intercoupling between the flexible hoses of an anesthesiology machine and the input connector of an endotracheal tube is disclosed. The breathing circuit connector consists of a hollow body of relatively rigid material having a cylindrical male input section and a cylindrical female output section. A cylindrical bore within the hollow body extends between the cylindrical input and output sections. The bore within the cylindrical output section consists of a series of two or more cylindrical portions having different internal diameters. The internal diameter of the first bore portion adjacent the output end of the cylindrical output section is slightly larger than the internal diameter of the bore portion situated within the cylindrical output section. The breathing circuit connector may be formed as an elbow with the longitudinal axis of the bore of the cylindrical output section being inclined relative to the longitudinal axis of the bore of the cylindrical input section. Alternatively, the improved connector may comprise a single female output section and a pair of cylindrical male sections, each section having a bore whose axis is displaced from the other to form a Y-shaped connector.
